I don't think one can equate one with the other. Meaning, just because one doesn't read EVERY SINGLE horrific story in the news means they have their head in the sand about the ills of society. 
In addition, If one continues to keep focusing or finding all of this deplorable mess, in the news, one may begin to believe that there's nothing that can be done.
Bottom line, I agree that there should be some type of disclaimer attached to these types of posts and allow folks to choose.
BTJM. 
I can't agree with the first part. But, as for the part in bold, of course I agree that might be a good idea (as stated earlier). But, wouldn't that be rather difficult to regulate? What about the newbies or even regulars who "didn't get the memo"?
Maybe we should just avoid clicking links until we can use context clues from other posters to ascertain what the link will be about? For those of us who prefer to avoid upsetting news, I mean...
Using this thread as an example, after a few posts, it was clear that this article was sad news. After a few more, it became even clearer what the article was about. So, folks really didn't have to click it in order to know what it was about, at that point. Maybe the folks who are more sensitive to bad news should just wait a little bit before clicking.
